Patented Feb. 27, 1945 UNITED STATES PATENT OFFICE GLASS CUTTINGv APPARATUS Joseph Joss, Douglas, Ariz. Application January 8, 1943, Serial No. 471,719 1 claim. (c1. sai- 16) This invention relates to new and useful improvements in glass cuttingdevices and more particularly to means whereby glass can be cut I crosswise and lengthwise conveniently and accurately.

[in important object of the invention is to pro vide a simplified glass cutting board and straight edge which can be manufactured and retailed at a low price.

Other objects and advantages of the invention will become apparent to the reader of the following description.

In the drawings:

Figure 1 represents a top plan view showing the board with the straight edge disposed cross wise, the straight edge being shown in broken lines disposed lengthwise of the board.

Figure 2 is a fragmentary bottom plan view of the board and straight edge.

Figure 3 is a section on the line 3-3 of Figure 1.

Figure 4 is a section on the line 4-4 of Figure 3.

Figure 5 is a fragmentary side elevational view of the straight edge.

Referring to the drawings wherein like numerals designate like parts, it can be seen that numeral 5 denotes a board made up of a rectangular-shaped frame 6 consisting of side members a, a and end members b, b. Suitable brace or jaw members 'l may be employed in the frame to reinforce the same.

Suitable graduations B are provided on all of the frame members at the top surface thereof and suitable guide markings 9 are disposed transversely and longitudinally on a top l0 which fills the frame 5, this top l0 having its top surface below the top surfaces of certain frame mem bers.

Numeral Il generally refers to a straight edge, the same comprising an elongated bar l2 provided atone end with a rectangular-shaped block I3 the end portions of which project laterally beyond opposite sides of the bar i2. The block i3 has openings in the end portions thereof to receive guide rods I4, IB each of which is headed as at l5. l

Slidably disposed on the bar l2 adjacent the block i3 is a block i6 and the rods i4 have threaded end portions I'l for disposition into the end portions of the slide block i6. Coiled oompression springs i8, I8 are interposed between corresponding end portions of the blocks I3, l5. The remaining end of the bar l2 has a cleat I9 at its top side, somewhat inwardly from the A second cleat 20 is secured to the underside of the bar i! at the extremity thereof and as shown in Figure 5, and this is to abut the end portions b of the frame 5 when the straight edge is employed in a longitudinal position.

In the use of the device, it can be seen that the block i6 is placed against, say one side portion a of the frame and a pull exerted longitudinally on the bar i2 so as to compress the springs IB whereupon the bar is lowered so that the corresponding cleat I9 can engage and abut the opposite side portion of the frame. This is, of course, after proper placement of the bar I2 has taken place in order that the proper size piece of glass can be cut.

While the foregoing specification sets forth the invention in specic terms, it is to be under stood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the invention, what claimed as new is: l

In glass cutting apparatus, a board having side edges, a straight edge adapted to extend across the board and having an abutment thereon ad jacent one end for engagement with one side edge l of said board, and detent means on the other-end of said straight edge for clampinglyengaging the other side edge of said board comprising a pair of elongatedvlike blocks extending crosswise of said straight edge and one fixed on said other end of the straight edge and forming a T-head thereon, the other block having said straight edge slidably extended through the center thereof and being substantially thicker than the straight edge for engagement with said other side edge of the board when either face of the straight edge is opposed to said board, a pair of headed pins slidably extended through the first-mentioned block alongside opposite side edges of the straight edge and having ends xed in the second-mentioned block, and coil springs eircumposed on said pins intermediate said blocks.
